iris: Drop stale syncobj references in fence_server_sync

When calling glWaitSync (fence_server_sync), we added dependencies
in all batches (render and compute) on existing work.  Even if
applications don't use compute at all, they theoretically could,
so we record that the compute batch depends on the render batch.

But if the application truly doesn't use compute, or rarely uses
it, we ended up recording dependencies on _all_ previous render
batches, racking up a massive list of syncobjs.  Not only is this
pointless, it also meant that we never allowed the kernel to free
the underlying i915_request objects.

There are a number of solutions to this problem, but for now, we
take a simple one: when recording a new syncobj dependency, we
walk the list and see if any of them have already passed.  If so,
that dependency has been fulfilled.  We no longer need to track it,
and can simply drop it from the list, unreferencing the syncobj.

Android's SurfaceFlinger in particular was hitting this issue,
as it uses glWaitSync, doesn't typically use compute shaders,
and runs for long durations.

Thanks to Yang A Shi <yang.a.shi@intel.com> and
Kefei Yao <kefei.yao@intel.com> for their excellent work in
tracking down this issue!

As with a6xx (commits beb02a78, 5785bcc8), the blob doesn't set this flag
for a5xx when fragcoords are used but not proper varyings.  See for

nvc0: Add shader disk caching

Adds shader disk caching for nvc0 to reduce the need to every time compile
shaders. Shaders are saved into disk_shader_cache from nvc0_screen structure.

It serializes the input nv50_ir_prog_info to compute the hash key and
also to do a byte compare between the original nv50_ir_prog_info and the one
saved in the cache. If keys match and also the byte compare returns they
are equal, shaders are same, and the compiled nv50_ir_prog_info_out from the

panfrost: XMLify the rest of shader_meta

This contains a bit of everything, so just XML for this commit. The rest
of the series will be slowly moving over to this representation.

The one noteworthy addition is the rename of "No MSAA" to
"Single-sampled lines". This came about due to a buggy branch that
forgot to set this bit. Ths worked, with the caveat of the following
tests failing with a single-sampled framebuffer:

   dEQP-GLES2.functional.rasterization.interpolation.basic.line_loop_wide
   dEQP-GLES2.functional.rasterization.interpolation.basic.line_strip_wide
   dEQP-GLES2.functional.rasterization.interpolation.basic.lines_wide
   dEQP-GLES2.functional.rasterization.interpolation.projected.line_loop_wide
   dEQP-GLES2.functional.rasterization.interpolation.projected.line_strip_wide
   dEQP-GLES2.functional.rasterization.interpolation.projected.lines_wide
   dEQP-GLES2.functional.rasterization.primitives.line_loop
   dEQP-GLES2.functional.rasterization.primitives.line_loop_wide
   dEQP-GLES2.functional.rasterization.primitives.line_strip
   dEQP-GLES2.functional.rasterization.primitives.line_strip_wide
   dEQP-GLES2.functional.rasterization.primitives.lines
   dEQP-GLES2.functional.rasterization.primitives.lines_wide

That is, this bit controls the behaviour of line rasterization with
multisampling. This is required to implement the divergent behaviours
described in the OpenGL ES 3.2 specification sections 13.6.1 ("Basic
Line Segment Rasterization") and 13.6.4 ("Line Multisample
Rasterization"), where setting this bit corresponds to the former
(single-sampled) behaviour.

panfrost: Fold work_count packing for blend shaders

It's annoying this is needed at all, but that's life for you.

panfrost: Use pack for shaderless

We'll need a more aggressive refactor for this soon, I think.

panfrost: Use packs for fragment properties

A bit more complicated, since there are dependencies on other state (for
early-z and discard handling). We separate this cleanly to help defer
packing later.

panfrost: XMLify Midgard properties

In a long journey to a full XML representation of mali_shader_meta,
let's start with the fourth word, containing some shader properties.
This is a translation from panfrost-job.h, with the exception of
widening the uniform buffer count field [1]

The other noteworthy change is combining the unknown 0x20 flag with the
WRITES_Z flag to form a 2-bit depth source. This papers over the fact
that the blob zeroes this field for non-fragment shaders. Given the
proximity, this is a reasonable guess and avoids an ugly "is_fragment"
bit.

[1] Justified by the increased limit advertised by the Vulkan blob
(maxDescriptorSetUniformBuffers on
https://vulkan.gpuinfo.org/displayreport.php?id=5602#limits). Not
actually supported in Panfrost right now.

panfrost: Clean up blend shader errata handling

The cases of SFBD blend shaders (which work normally) and MFBD blend
shaders (which need a bizarre errata workaround) are distinct. Let's
seperate them to make each a bit clearer.

Since this field is repurposed on Bifrost, this should fix bugs there
too (although blend shaders on Bifrost are currently todo).
